lar flanges 3 and 4 on. the; shells embrace the', ends of the spokes 5 and have rivets 6,',6-

extending therebetween through ting faces of adjacent spokes Within the shells 1 and 2 is the tiller or core 7, preferably of Wood, which has radial slots therein for receiving the inner ends of the spokes 5, in accordance with a practice well known in the art.-

. The assembled hub is bored out for the reception of the axle box 9 which consists of the tapering sleeve portion 10 and the enlarged end portion 11 shown at the left in Fig. 1. Extending longitudinally from the enlarged portion 11 are two or more 'feathers or splines 12, 12, integral with the axle box 9, which become embedded in the fibrous core 7 when the axle box is drawn the abut groove.

In Fig. 2 I have shown a modification wherein I contemplate having the locking pin revolubly mounted in the collar 16. In this adaptation the diametrical hole through the collar 16 is made slightly larger than the diameter of thepin, as shown in exaggeration, and the pin is bisected at its center.

The two pins 26 and 27 are required because the turning moments applied tov their outer extremities by the revolving axle box are in op osite directions.

and 32, which afford more extlensivesurface for engagement with the sides of the internal width, The pin, which in this instance acts as a pivot for the rollers, may be mounted in the collar 16 either rigidly or revolubly as .previousl explained. The insertion of this pm is e eoted through the removal of the. screw 21' and the insertion of the rollers is ef fected through the removal of the screw 22 Where subjected to severe usage, it may be preferable to aline the internal groove 18 and the dia-Inetrical hole 23 so that the pins or rollers'can bear only on the left side of 1 the groove, as illustrated in Fig. 3, to receive the single thrust acting therebetween. When so constructed the inwardly-acting thrust would be taken up by the taper of the spind'le 14: and collar 16 and by the abutting shoulders on the spindle and in the axle box. In Fig. 3 the collar 16 is cylindrical to provide a straight seating surface for the rollers;

The strength of the spindle is not impaired by the diametrical hole therethrougli,

as the enlarged collar 16 provides ample reinforcement therefor.

Referring to Fig. 1, the end cap 13 is internally threaded but partway, the remaining portion serving as a reservoir for lubricant which is injected through the oilcup 34, threaded into the outer face of the end cap 13. During rotation of the hub the bodyof oil has constant access to the-longitudinal groove 35 in the spindle 14, thereby provid-- have supplemented the revoluble feature of Fig. 2 by providing rollers 31 oove. Thainternal groove is necessarily widened to accommodate their greater dle bearing. The end cap 13 closes off the outer end of the axle box thereby preventing the entr of dirt and foreign matter to the spindle aring.

What I claim is:

1. In combination, an axle box having a groove therein and having a radial hole alined with said groove, a screw normally closing said radial hole, a spindle in said axle box, and a. freely turnab'le pin through said spindle having its ends engaging in said groove.

2. In combination, an axle box having an internal groove therein and having aradial hole alined with the groove, means normally closing said radial hole, a s indle in said axle box, and two alined pins reely turnable in said spindle and having their outer ends in said groove.

3. In combination, an axle box having an annulargroove thereinand having a radial hole alined with the groove, means normally closing said hole, a spindle in said box and members projectin 'into said roove.

4. In a wheel htib, an axle ox having an annular groove therein and having aradial hole alinedwith said groove, a screw normally closing said radial hole, a spindle in said axle box, locking means on said spindle engaging in said groove, an outer shell inclosing said axle box and fixed thereon independent of said screw, said outer shell havin an o ening therethrough alined with sa d radia hole and said screw. 5. In combination, an axle housing having an annular groove therein, a. spindle in the housing,- support means in the spindle radially projecting into the groove, anti-friction nreans carried by first said means, the housing having openings therein adapted to aline with said support means, and removable pliigs in said openings. to permit removal of said so port means.
